When the currently shown page is the chat of a certain room,
prevent that room from moving around in the left pane due to new
messages/activity or unread/highlight counters change.
When the user switches to another page/room, the previously held lock is
released and that room completes all the moves it would have done if it
wasn't locked.
This makes navigating a room list with lots of activity easier, and
prevent annoyances like clicking on a room with unread messages and
having it immediatly fly down the list (possibly out of scroll view).
Pin/unpin is more representative of what the function actually does
for rooms in the left pane. Also change the corresponding icons and
renames the config file section: RoomList.Bookmarks → RoomList.Pinned
Downloading file messages will now show a transfer control above the
composer, similar to uploads. Measuring the progress or pausing the
operation is not possible yet.
When hovering on stability percentages in the server browser, a tooltip
now shows the total downtime in the past 30 days, number of incidents,
their average length and the longest's duration.
If a model has tuple keys, these already get turned into JSON strings
for the ModelItemSet pyotherside event (for QML and JS reasons).
Do the same for ModelItemDeleted's ids field, else the QML event handler
will be unable to find the items by IDs.
Introduce a bookmark system for rooms:
a room bookmarked will always appear on top of every other
(for a given account).
Bookmarking can be done through context menu on targeted room
(as well as un-bookmarking) or through settings.json
(key roomBookmarkIDs) for permanent bookmark.
roomBookmarkIds is a {account_user_id: [room_id]} dict.
Fix the AutoCompletedMembers filter model to ensure that it doesn't
pick all the items from the corresponding room member model on startup,
wait until the user actually uses the completion feature to fill it.
This required us to set the media downloaded local path on events
entirely from python instead of simply lazy-fetching them when needed
from QML, due to pyotherside's async nature and files that must be open
in a certain order.
